HINGED GUY-CLAMP.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed November 15, 1915. Serial No. 61,711.

To all whom t may cof/cern Be it known that l.. Jasmin BLACKBURN, acitizen of the United States, and resident of Webster Groves, Missouri,have invented certain new and useful improvements in Hinged Guy-Clamps,of which the following is a specification Containing' a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof,

My invention relates to improvements in hinged guy clamps wherein aplate, arranged to be secured to a pole is provided with bearings inwhich, to pivotally or hingedly support a. guy clamping means comprisinga tapering socket and wedge.

The object of my invention is to construct a simple inexpensive andeasily operated guy clamp which may automatically adapt itself todifferent arrangements of guys; and to arrange a guy clamp comprising atapering sock-et and wedge, wherein an eiiicient, and easily operatedmeans is employed for holding the wedge in different positions relativeto the socket.

With the above object in view, my invention consists in certain noveldetails of construction and arrangement of parts as hereinafter fullydescribed, pointed out in my claims and illustrated by the accompanyingdrawings, in which- Figure 1 is a side elevation of a device embodyingmy invention, a fragment only of a pole being shown;

Fig. 2 is a frontor face view of the device;

Fig. 8 is a longitudinal sectional elevation of the device taken throughthe approximate center thereof;

Fig. 4C is a transverse sectional plan of the device taken through theapproximate center thereof;

Fig. 5 is an end view of the socket alone;

Fig. 6 is a vertical sectional elevation of the socket;

Fig. 7 is an end view of the wedge alone;

Fig. 8 is a side elevation of the wedge;

Fig. 9 is a plan of the wedge;

Fig, 10 is a vertical sectional elevation of the socket and wedge with asection of guy therein showing the Wedge held against inward movementrelative to the socket, to permit movement of the guy over the wedge;

Fig. 11 is a sectional plan of the socket and wedge showing a tap screwin position to hold the wedge against movement inwardly relative to thesocket, and

Fig. 12 is an elevation on a reduced scale showing the whole structureof my invention employed as a guy clamp, and the plate of my inventionas used for supportinga guy to prevent splitting of a wooden pole.

Referring by numerals to the accompanying drawings, 15 designates aplate of substantially rectangular formation, and whose cross section isarcuate to conform to a pole, and which plate has on its rearmost facespurs 16 to assist in the holding of the plate in position on a pole andthrough which plate there is formed openings 17 for the further orpermanent securing of the plate to the poles by use of lag screws,spikes, or the like,

Formed through the center portion of this plate there is an aperture 18through which a guy is to be passed. Outstanding from the plate and oneach side of the aperture 18 there is formed a bearing 19 andoutstanding from the plate above the aperture 18 is a channeled guysupporting lup' 20.

The numeral 21 designates a socket which tapers from end to end, isformed hollow throughout and in cross section is substantially oblong`with parallel sides and rounded ends. On each side of the socket and eX-tended beyond. the body thereof is an integral trunnion 22 which isarranged to seat in the bearing 19 of the plate to permit of a pivotalor hinged movement of the socket relative to the plate.

In the one side wall of the socket there is a way 23 which opens to theinterior of the socket and parallels the median line thereof. In thisway 23 adjacent the larger end of the socket there are the shoulders 24.

In the opposite wall of the socket arranged along the median linethereof is one ormore tapped openings 25 arranged to receive a set screw26 for the purpose of holding the wedge block 27 with its feather 28seated in the way 23 and with its shoulders 29 against the shoulders 24of said way whereby to hold the wedge outwardly relative to the socket21 as clearly shown in Figs. 10 and 11, to permit easy movement of theguy around said wedge and through said socket. In the wall of thesocket, having the way 23, there is a tapped opening 30 intersectingsaid way for the purpose of receiving the tap screw 26 whereby the tapscrew may be employed te move the wedge to free its feather from saidway and permit the wedge to be drawn by the guy into said socket toclamping position.

The device of my invention is designed primarily for use in connectionwith guys extended! through openings formed in Wooden poles and .in viewof the fact that different arrangements of guys necessitate the formingof said openings through the poles at different angles such for instanceas horizontally through the poles as show-n in Fig. 3,. or diagonallythrough a pole as shown in Fig. l2.

have found it advantageous to hingedly or pivotally support the guyclamping means so that the clamping means may be held in substantialalinement with the guy, which arrangement obviates angles or bights inthe guy offering resistance to the movement of the guy through theclamping means in adjusting the guy as well as obviating anvgleS tendingto break the wire or at least mar its protecting surface such asgalvanizing. r

Having thus described my invention what I claim as new therein anddesire to secure by Letters-Patent of the United States therefor is 1.ln a device of the class described, a tapering socket having openingsthrough opposite walls thereofa an axial way formed in one of saidwalls, and an offset shoulder Y in said way, a wedge having'lessthickness than the distance between said opposed walls Gopies ofvthispatent may be obtained for ve cents cach, by addressing the Commissionerof Patents,`

of the socket andra feather having an offset shoulder arranged tocoperate with said way and shoulder for holding the wedge againstmovement relative to the socket.

2. In a device of the classdescribed.y a tapering socket having tappedopenings in its opposite walls, a way inone of said walls intersectingsaid tappedV opening and a shoulderin said way, a wedge for inser-` tionin said socket, a shouldered feather on said wedge, and a screw arrangedto be inserted in one or the other of said tapped openings to engage thewedge to either'hold its feather and shoulder seated in the way Y,

socket, substantially as shown and for thev purposes stated.

ln testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
